Schematic set in a RAR archive for Dell Latitude E5470 and E5570 and Precision 3510 laptops, with a further model listed in the name as E520. The listed Compal board numbers are LA-C621P and LA-C641P, and LA-632P and LA-621P are also extracted from the name. Use the diagrams to trace power rails, check the charging and power-on sequence, and locate the cause of shorts. Compare the board code silkscreened on your motherboard with these numbers before trusting a page, as related platforms differ in detail.
